Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The main goal of the study is to investigate the feasibility of the VRelax tool and to evaluate the efficacy of the tool for reducing subjective and objective stress, as preparation for a larger RCT. - Subjective stress: baseline and after last session: Perceived Stress Scale, a 10-item scale to measure the degree to which situations in the last week have been appraised as stressful. Before and after each session: ecological momentary assessment single items, assessing perceived stress, anxiety, paranoia, positive and negative affect on a 1-7 ordinal scale. - Physiological stress Heart rate (HR) and skin conductance level (SCL) are recorded on the non- dominant hand in standing position for 5 minutes at baseline before session 1 but after introduction of the VRelax tool, and for 5 minutes after the first and after the last session. Skin conductance level (SCL) is measured using a sensor with two finger electrodes on the middle and ring finger of the same hand with a sampling rate of 10 Hz. Heart rate (HR) is assessed by non-invasive pulse wave measurement using a Nexus 4 with a photo-electric plethysmograph on the index finger. - Feasibility and user-friendliness will be measured using a qualitative interview after the last session (e.g., are enough patients willing to participate?, technical problems, was the intervention pleasurable / helpful, was the frequency and duration of sessions appropriate?). | — |
